Editing made visual
Open your notes on a simple grid, drag them into place, and hear the result straight away.
Higher notes sit higher on the grid and time runs from left to right. That makes it easy to spot a note that is too long, too early or on the wrong pitch.
Handy tools help too: transpose moves a whole melody up or down, and quantize lines notes up with the beat.
After turning a recording into MIDI, a few notes are usually a little off. The MIDI editor shows each note as a block on a grid, so you can move it, shorten it or delete it with your mouse.
You can also open MIDI files you already have. When your melody sounds right, export it and use it wherever you like.

MIDI editor questions
Do I need to install software?
No. It runs in your web browser.
Can I open my own MIDI files?
Yes. Import a .mid file, edit it and export it again.
What does quantize mean?
It nudges notes so they line up neatly with the beat.
Is it a full music studio?
No. It focuses on editing notes; mixing and recording happen elsewhere.
